Here is the formula I use.You can make your own spray,,scentless soap,,bake soda,,Hydrogen peroxide, and rain or distilled water. this helps kill odors and bacteria. I shower with scent free soap and bake soda. All helps some. You will always put out some scent but you can cut down on it. Some deer very skittish to any scent some tolerate some.
The deer that are alerting when you use ozonics.Hunting down in SW Alabama where pine is dominant I usually crush pine needles and rub them on my clothing before I get in the stand. I also use ozonics to dry-wash my hunting clothes and spray some scent blocker on my boots.
I was using ozonics in the stand, but I've had deer alert to it several times. Plus I think they hear the fan running which is loud enough to affect my ability to hear deer sneaking through the brush. I think it's good technology and scientifically sound - ozone kills odors - but I think the deer can tell something odd is going on. Like I said, I'll continue to use it as a dry-wash, but won't tote it to the field.
